Like letters of reference refer to like parts in the several figures, and furthermore the 10 .parts shown herein are desi ated by the same reference characters as t e corresponding elements in tliep'lrent case above referred to.

General adding The'reference-numeral 40(Figs. 1 and 2) denotes numeral keys arranged in denominational rows and depressible to set 11 items or amounts for entr into a series accumulator wheels 2 ig. 2). Each row of numeral keys has associated therewith a key lever 36, 37 the vertical arm 37 of which is provided with a series of stop shoulders 39 and the horizontal arm 36 of which extends below the corresponding row of keys for operation by any key in said row. Also associated with each row of keys is 9. corresponding one of a series of controlling arms 30 pivoted on a cross rod 31 and coo crating with the related key lever 36, 37. ormally each controlling arm stands in the position shown in Fig. 2, wherein a lug 33 on said arm is engaged by a shoulder 38 on the rear side of the arm 37 of the associated key lever. Upon depression of any numeral key in the corresponding row, the key lever is turned, disengaging said shoulder 38 from lug 33 of said controlling arm and bringing into the path of a lug 34 on said arm a stop shoulder 39 corresponding-to the key depressed. Upon then operating the machine by drawing forwardly the operating lever 21 (Fig. 16) said controlling arm is drawn downwardly until stopped by the engagement of its lug 34 with that stop shoulder 39 that has been positioned in its path.

Connected with each controlling arm 30 through lugs 46 and 50 is a toothed segment adapted to engage and actuate a corresponding one of a series of pinions 4 attached to the respective accumulator wheels 2. The segments 5 are mounted on a cross rod 7 and are shiftable forwardly and rearwardly with respect to the controlling arms for engagement with and disengagement from the respective pinions 4. .Said segments 5 are also adapted to turn on said cross rod 7 and it will be seen that the positions to which said segments are movable about said rod are controlled by the arms 30, in conjunction with the respective key levers; the latter, in turn, being settable by the numeral keys.

The cross rod 7 above referred to is carried by rock arms 8 pivotally mounted on a shaft 9. Normally said rock arms and rod 7 are maintained rearwardl with the. segments 5 disenga ed from't e accumulator pinions 4, b springs 11 (Fi 13); but by turning of t e operatin handle 21 said segments may be engage with" said pinions. The handle 21 aforesaid is secured to one end of the shaft 20 (Figs. 2, 13, and 16), to which shaft a frame 15 (Figs. 2 and 16) and a frame 29 (Figs. 13 and 16) are attached. During the initial forward rocking of said handle 21 the frame 15, through its attached cam plate 14, acts upon a roller 18 on an arm 13 extending rearwardly from one of the rock, arms 8, whereb said arms 8 and cross rod 7 are thrown orwardliy and the actuating segments 5 are engage with the respective accumulator pinions 4. As forward rocking of said handle 21 continues, the rear walls of notches 28 in the frames 15 and 29 come into engagement with a cross bar 25 carried by rock arms 24 loosely mounted on shaft 20, and rock said bar 25 downwardly and forwardly. Such lowering of said bar 25 moves downwardly a cross rod 22 connected thereto and underlying the segments 5, and also exerts a. downward pull upon springs 27 connecting said bar 25 and said segments. Thereby, those segments 5 whose controlling arms 30 have been freed by depression of numeral keys are moved downwardly together with their controlling arms, through extents commensurate with the setting of the key le vers; and the accumulator pinions 4 are turned by said segments through corresponding extents whereby the amount set up on 10 the keyboard is added to the sum formerly standing upon said wheels.

At or near the end of the forward movement of the operating handle 21, the cam 14 on frame 15, moves clear of the roller 18 105 on arm 13, whereupon springs 11 draw the arms 8 backwardly to their position shown in Fig. 2; thus disengaging the actuating segments 5 from the accumulator pinions. During the rearward or return rocking of 110 handle 21, the shaft 20 and frames 15 and 29 rock rearwardly, the arms 24 are rocked to raise the lifting rod 22, and the actuators 5 and controlling arms 30 are restored to their normal position. The cam 14 is pivot- 115 ally mounted on the frame 15 and rides idly over the roller 18 during the rearward or return rocking of said frame, said cam dropping behind said roller into its position shown in Fig. 2 at the end of said return movement. 120

For a more detailed description of the operation of accumulating, reference may be made to the parent case (Patent No. 1,429,201)

hereinbefore referred to.

Recording mechanism For the purpose of recording the numbers WlllCll are added together by the above described mechanism a recording mechanism is Y provided which is constructed as follows:

- or other article is placed, which receives the record 141 represents a number of type segments which are arranged transverse y si e by side, below the platen and which are pivoted at their front ends to the supporting bar 31 upon which the rear ends of the controlling arms 30 are pivoted. Each of these type segments is provided at its rear end with a segmental row of type carriers 142, which are capable of moving radially back and forth on the type segment.

Each of the type carriers is provided at its rear end with a type and is guided upon the type segment by means of screws or rivets 143 (Figs. 3, 8 and 9) secured to the type carrier and arranged in radial slots 144 formed in the type se ment. Each of the type carriers is held in its inward or retracted position by means of an S-shaped spring 145, which is arranged between the carrier and the type segment and is secured with one end to the carrier and with its other end to the type segment, as shown in Figures 8 and 9. Upon raising or lowering the type segment any one of its type can be brought to the printing point or line, and upon striking the back or inner end of the type-carrier, when the same is in line with the printing point the type carrier will be driven outwardly and-its type will produce an impression on the sheet supported by the platen. After the carrier has received the blow for driving the same against the platen, the carrier is again quickly retracted to its I innermost'position by means of its spring.

'Each of the type segments is connected with one of the controlling arms, so that upon depressing a controlling arm and the registering gear segment connected therewith, the companion type segment will be raised and present one ofits type to the printing point.

For convenience in operating the machine, the keys are separated a considerable distance on the key-board and in order to produce a compact record, the printing segments are arranged closer together than the keys and the registering mechanism. In order to permit of this arrangement, each type segment and its corresponding controlling arm are connected by a connecting arm 146, as represented in Figures 1, 2, and 12. The connecting arms of the central controlling arms and type segments are comparatively stralght, but the connecting arms of the outer type segments and controlling arms are arranged obliquely, the degree of this obliquity gradually increasing from the central type segments and controlling arms in opposite directions toward the outer type segments and controlling arms, as represented in Figure 1.

The connecting arms 146 of the outer controlling arms are arranged-in the spaces behind t e upright parts and above the horizontal parts of the controlling arms, thereby permitting the inner .controllin I arms to move up andtdown without inter ering with the connecting arms 146 of the outer controlling arms.

he types on each type segment are arranged to correspond with the teeth and numbers of its companion gear segment and registering dial, the zero type being at the upper end of the series and the progressively higher digits arranged in their order;down-' wardly from the zero type. When the registering gear segment is in its highest positlon it presents its zero tooth to the dial pinion, and the type segment, which at this time is in its lowest position, presents its zero type to the printing point. Upon depressing a gear segment so as to present one of its igher teeth to the dial pinion, its companion type segment is raised proportionally and presents a corresponding higher numbered type to the printing point.

147 represents a number of hammers whereby the type-carriers are struck for driving the type against the platen. One of these hammers is arranged adjacent to each type segment and is provided with a head which is arranged in front of the series of types, and in line with the printing point of the platen. Upon shifting the type segment so as to bring one or another of its type carriers to the printing line and then operating the hammer, the latter delivers a blow against the inner end of the particular carrier which is at the printing point and produces an impression of its type on the platen. The several hammers are pivoted on the transverse rod 12, arranged in rear of the segments; and each of the hammers is yieldingly held in its forward position by aspring 148 connected at its lower end to a cross-bar 149 and at its upper end to a depending arm 150 on the hammer.

151 represents a Vertically movable trip baror rod which is arranged transversely below the hammers and whereby the latter are operated. This bar is supported at its ends upon the rear ends of rock arms 152 which turn loosely with their front ends on the rod 31 supporting the type segments and controlling arms.

153 represents a number of hammer or trip pawls, whereby the hammers are retracted preparatory to delivering a blow against the type carriers which are at the printing point.

i is provided in front of its pivot adjacent to the upper end of the hammer pawl with a lower trip lu or shoulder 156 and an upper trip lug or s oulder 157. When the parts are at rest, the hammer pawl 153 israised into its highest position and the hammer is in its normal position with its .lower trip lug 156 below and in rear of the hook of the hammer pawl and with its upper shoulder 157 in rear of the trip face of the hammer pawl,'as represented in Figures 2, 3, and 15.

Upon shifting the hammer pawl rearwardl while the parts are in this positionyso that its hook overhangs the lower shoulder 156 of the hammer, and then pulling the hammer-pawl downwardly, the hook of the hammer pawl engages with the lower shoulder of the hammer and turns the same so that its head is retracted from the type-carrier at the printing line. As the hammer moves downwardly with the hammer-pawl, the upper shoulder of the hammer comes into engagement with the trip-face of the hammer pawl and during the continued downward movement of the hammer and its pawl, this upper shoulder gradually crowds the hammer-pawl forwardly with reference to the hammer by reason of the hammer and its pawl swinging on difierent centers. During the last portion of the downward movement of the trip-bar 151 and the hammer pawl mounted thereon, the pawl is crowded forwardly by the upper shoulder 157 of the hammer to such an extent that its hook is disenaged'from the lower shoulder 156 of the hammer, thereby liberating the latter and permitting its spring 148 to throw the same quickly and deliver a blow against the t pe carrier at the printing line. The tripar 151 now rises and carries the hammer-pawl into its highest position, preparatory to again engaging the hammer for depressing the same.

158 (Fig. 3) represents a number of upright shifting arms whereby the hammer pawls are moved rearwardly, so that their hooks engage with the lower shoulders of the hammers. One of these arms is arranged adjacent to each hammer pawl, as shown in Figures 3, 6, and 15, and is pivoted at its lower end on the trip-bar 151, and its upper end is provided with a roller or projection 159 which bears against a hammer cam 160 on the lower part of the adjacent type segment, as shown in Figures 3,7, and 12. This hammer cam is provided at its upper end with a receding or low portion, an inclined portion arranged below the low portion, and a concentric or high portion arranged below the inclined portion. Each shifting arm 158 is moved forwardly and its roller is yieldingly held in engagement with the adjacent hammer cam by a spring 161 connecting said arm with a cross-bar 162. secured to the rock arms 152, as represented in Figure 7 The backward movement of each hammer pawl with reference to its com anion shifting arm, is limited by means of a step 163 secured to the upper portion of the hammer pawl and engaging with the front side of the shift arm as represented in Figures 3, 5, and 15.

Each hammer pawl is yieldingly held in its rearmost position with reference to its shifting arm by means of a C-shaped spring 164 secured with its ends, respectively, to the hamer pawl and its shifting arm, as shown in Figures 2, 3, and 15. 'In the lowermost position of a type segment the recedin part of its cam is presented to the roller of t e shifting arm 158, which permits the hammer-pawl to be retracted into its foremost position, as represented in Figure 2. Upon depressing the trip-bar 151 when the parts are in this position, the roller 159 is not engaged soon enough by the incline of the cam 160 to engage the hook of the hammer pawl with the lower shoulder of the hammer, before the hook has passed below this shoulder; but instead, the trip face of the hammer pawl slides idly against the shoulder 156 without retracting the hammer, whereby no impression of the particular type at the printing line is produced. If the type segment is raised, so as to present one of its lower types to the printing point or line, the incline of its cam, during the first part of the upward movement of the segment. moves the shifting arm 158 rearwardly together with the hammer pawl yieldingly connected therewith, so that the hook of the hammer pawl stands over the lower shoulder 156 of the hammer. Upon now depressing the pawl 153 the hammer will be retracted and released near the end of the downward movement of the pawl, and will be quickly swung up by the spring 148, thereby delivering a blow against the type at the printing point and producing an impression thereof. The incline of the type segment cam is so constructed that it throws the hammer pawl backwardly into an operative position when the segment is raised one digit space, and during the continued upward movement of the segment, the hammer pawl is held in this operative position by the high concentric part of the segment cam." By thus constructing the type segment cam its companion hammer pawl is not shifted when the segment is not raised and its zero type remains at the printing line, but the hammer pawl is shifted into an operative position for producing an impression, if the type-segment is raised one or more digit spaces and presents any one of its digits higher than zero to the printing line.

automatically. One of these transfer-fingers is secured to each of the shifting arms 158, as

Figure 18. If any one .of the printing segments remains in its lowest position, so that its cipher remains at the printing line and the next higher printing segment has been raised for printing a higher number or digit, the transfer finger of the higher hammer shifting arm 158 while being moved rearwardly by the cam of its companion printing segment, is caused to engage with the shifting arm 158 of the next lower hammer pawl and shift the latter backwardly, so that its hook is carried backwardly over the lower shoulder of the companion hammer. Upon now depressing the trip-bar 151, the higher hammer pawl 153 is coupled with its hammer, and the next lower hammer pawl is also coupled with its hammer, whereby an impression of the cipher or zero type on the lower segment is produced on the platen at Y the same time that the next higher number is printed on the platen.

If two ciphers occur in succession in the body of a number, the shifting arm to the left of the highest order printing segment to be operated for printing a zero sets the hammer mechanism of said highest zero-printing segment by means of the transfer finger of said shifting arm and the shifting arm of said highest zero-printing segment in turn by means of its transfer finger sets the hammer mechanism of the printing segment of next lower order, etc. This operation of producing an impression of the cipher type is effected automatically and renders it possible to print any number of ciphers in succession in the body of a number-because the hammer operating mechanism of each segment which remains standing with its upper type at the printing line is controlled by the hammer operating mechanism of a higher type segment and in turn controls the hammer operating mechanism of the next lower type segment, if thenext lower type segment presents a cipher to the printing line.

Only the ciphers below the highest digit in the number to be recorded are thus printed automatically because the printing of' a digit depends upon the upward movement of av printing segment, thereby avoiding the printing of ciphers ahead of the highest digit in the number to be recorded. The hammershifting device of the segment which prints the numbers representing units of cents is,

preferably, not provided with a transfer finger to operate on the hammer-shifting device of the segment which prints fractions of a cent, because it is properthat the space to the right of the lowest integer shall remain blank when no fraction is recorded therein. r

The carrying-bar 151 is. raised by one or more springs 166 '(Fig. 13) which connect this bar with the transverse rod 12, and the u ward movement of the bar 151 is arrested w en the hammer-operating pawls reach their highest osition b a transverse bar 167 (Figs. 2, 3, 4, f, 13 and 18) which is engaged y the rear ends of the rock arms 152. 168 (Figs. 2 and 13) represents a coupling-hook, whereby the hammer trip devices are depressed, Y This hook is pivoted with its'upper end to the trip-bar 151 and its lower engaging end is provided with a notch having upper and lower shoulders.

In the lowered position of this hook its notch engages with a cross-bar 169 which is connected with the rock-arms 24, as represented in Figures 2 and 7 so that the hook and the hammer-operating devices connecting therewith are actuated from the rockingframes 15 and 29, throughthe medium of the rock arms 24. In the re'armost position of the rocking frames, the front ends of their notches, 28 bear against the front side of the bar 25 to which the gear segments are yieldingly connected, and the cross-bar 169 bears against the manor upper shoulder of the notch of the hook 168, as represented in Figure 2.

Upon swinging the rocking frames forward, the incline of the cam 14 first raises the rock arm 13 and shifts the gear segments into engagement with the dial pinions, and 7 of this hook. After the cross-bar 169 engages with the lower shoulder of the notch of the hook, the latter and the hammer-operating device connected therewith, are moved downwardly with the rocking frames until these frames reach the end of their downward movement. During the last portion of the downward movement of the rocking frames, the hammer-pawls are disengaged, as before described, from the retracted hammers, whereby the latter are released and strike the type-carriers which are at the printing line. By this means, the blow of the hammers is delivered after the registering of the numbers has been effected on the dials and the type-segments have been shifted into their proper position for recording the respective number.

- The hammers do not follow the type-carriers to the end of their outward movement but are stopped short, after delivering a blow against the inner ends of the carriers by their depending arms 150 engaging with a rubber- Figure 3, so that the types are moved outwardly by the impact of the hammers and are then returned by their springs so as to clear the printing surface.

Printing f totals totaley acts throngh elb'ow lever 80 (Fig.

13) and cords 81 an 82 to draw forwardly a lever 76 which is pivoted in the rearpart of the machine and has a forwardly extending portion adapted to coact with a tail iece 75 on the cam 14; whereby upon said orward movement of said lever the cam 14 is raised into an inoperative position wherein said cam is unable to cause engagement of the actuators 5 with the accumulator pinions 4. Also, depression of the total key 84, acts through cords 81 and 83 to rock a lever 78 to an ineffective position wherein a cam 67, pivotally mounted on frame 29 and normally held raised by said lever 78, is permitted to drop to its lower or operative position. When said cam 67 is in its operative position, its lower inclined portion 68 lies behind a roller 73 on an arm 72 extending rearwardly from one of a air of rock arms 66 secured to the shaft 9. gaid rock arms 66 carry at their lower ends a cross bar or bail 64 (Fig. 2). The

latter is connected by springs 65 with a plurality of feeling fingers 61 pivotally mounted on cross rod 35. The feellng fingers61 are provided with laterally extending lugs 63, which extend behind the corresponding key lever arms 37 and said feeling fingers are normally held with their upper portions in the rearward position by means of springs 60, which normally hold t e corresponding key lever arms 37 in rearward position as shown in Fig. 2. The feeling fingers 61 each cooperate with a corresponding spiral cam 57, each of which cams is'rotatable with a corresponding one of the totalizer gears 4. The surface of each cam'rises progressively from v a low point and terminates at a high point which is in radial line with the lowest point. As any cam 57 turns with its corresponding totalizer gear 4 it presents opposite the cor responding feeling finger 61 a portion of its surface which correspronds to the position of said totalizer gear. or example, if a totalizer gear stands at 1, the corresponding spiral cam 57 is positioned so that its lowest portion is opposite the corresponding feeling finger. If a totalizer gear stands at zero, the highest portion of its corresponding cam 57 is opposite the corresponding feeling finger. For positions of the totalizer gear between nine and zero, corresponding portions of said cam come opposite the associated feeling finger. It will now be seen that if the key 84 aforesaid be depressed, thereby rendering cam 14 inoperative and cam 67 operative, and the machine be then operated, the cam 67 will rock the arms 66 and bail 64 rearwardly, exerting a force through springs 65 on feeling fingers 61 whereby said feeling fingers are caused to assume posltions determined by the numbers standing on the corresponding totalizer gears, through the spiral cams 57 and the upper key lever arms corresponding to said feeling fingers are also positioned in accordance with the amounts standing on the total i'zer gears. If any totalizer gear stands at zero, the highest portion of its corresponding cam 57 is presented to the corresponding feelmg finger, as above pointed out, and prevents said feellng finger from moving forwardly, with the result that the corresponding key lever arm stands in the position shown in Fig. 2 with its stop shoulder 38 in the path of the lug 33 of the corresponding controlling arm. After the feeling fingers aforesaid have moved into contact with cams 57 and have thereby positioned the key levers in accordance with the amount or total standingon the totalizer gears, the further turning of shaft 20 and frames 15 and 29 draws downwardly the rod 22, as above described, and the segments 5 move downwardly out of engagement with the totalizer ears, until said segments are stopped by the ey levers in positions corresponding to the amounts standing on the respective totalizer gears. The type segments 141 have now been positioned so that numeral type corresponding to the amounts standing on the totalizer gears 4 are brought to printing position and when the hammers 147 are released, as above described, printing of said amounts is accomplished on the record sheet carried by the platen 140. In other words, the total of the numbers added on gears 4 is printed on the record sheet.

Duplicate printing by counterpart types For the purpose of permitting the numbers to be printed in duplicate, for instance, when it is desired to print an amount on a bank' check, and the same amount on a stub, the machine is provided with mechanism which is constructed as follows:

1410 (Figs. 1, 4, 16, and 18) represents a number of duplicate printing or type segments which are arranged transversely in line and preferably toward the right of the main printing segments 141, and which are pivoted loosel at their front ends on the supporting-r0 31. One of these duplicate number-printing segments is provided for each of the main number printing segments, and each duplicate segment is connected with its companion main segment by a U-shaped frame (Fig. 19) which is connected by the upper ends of its arms 189 to its duplicate and main segment and has its cross-bar 190 arranged transversely below the intervening segments, as shown in Figures 1, 2, 4, and

connectingwframes.of the several pairs of printing segments to be arranged compactly, the arms of the connecting frame are curved concentrically with the pivots of ,the segments, as represented in Figures 2 and 4.

Each of these duplicate printing segments is provided with type-carriers corresponding to and constructed the same as the type-carriers of its companion main segment and each of these duplicate segments is provided with a hammer-operating device which is constructed the same as the hammer operating devices of the main segments, and the same description and letters of reference, thereforeapply to the details of both the main and duplicate printing segments.

Duplicate printing inoperative plicate a horizontally movable bar 191 (Fig.

20) is provided, which is arranged transversely in rear of the hammer-pawls of the duplicate printing segments and which is provided with a number of forwardly proecting lugs or stops 192, as represented in lines in Figures 4, 18, and 20. Upon ing this bar, so that its stops stand in rea or the duplicate hammer-pawls, as shown in rail lines in Figure 20, these pawls are prevented from being swung rearwardly and operating the hammers. Upon moving this bar so that its stops clear the duplicate hammer pawls, as represented by dotted lines 192, Figure 20, these pawls are free to be swung rearwardly by the segment cams 160 into engagement with the hammers, so as to retract the same during the downward movement of the pawls for producing an impression of the types of the duplicate segments which are at the printing line. A suitable key or finger-piece is provided, by the operation of which the bar191 is shifted into effective position.

Platen mechanism -2, 13, and 17) arranged in rear of the printwith two upwardly and forwardly projecting arms 261 and with two upwardly and rearwardly projecting arms 262, as represented in Figures 1, 2, 13, 16, 17, and 18. The supporting sleeve is arranged to slide transversely on a rod or track 263 which is secured with its ends to the sides of the frame.

The platen is journaled in the upper ends of the front arms 2610f the paper carriage and is held in position at the printing line by means-of a catch 264 (Figs. 1 and 1 8) which engages with its front hooked end over a transverse rod 265 arranged below the platen and secured with its ends to the sides of the main frame as represented in Figures 1, 2, and 18. This catch is yieldingly connected with the paper carriage, so as to permit the platen to recede more or less from the printing mechanism for the purpose of ad-' usting the platen to the thickness of the sheet of paper or other objectwhich receives the impression and which is interposed between the platen and the printing types.

When printing upon a sheet of paper, this sheet is fed forwardly underneath the platen and upwardly in front of the same, so that the sheet passes the printing line. The sheet is pressed against the under side of the platen, in rear of the printing line, by a transverse presser roller 270 (Figs. 2 and 13) arranged below the platen and journaled with its ends in the front arms 261 of the paper carriage.

Plated feed or line spacing 283 (Figs. 1, 13, 16, and 18) represents a platen feed lever which is pivoted loosely on the left end of the platen shaft and which is provided on its rearwardly projecting arm with a pawl 284 which engages with a ratchet Wheel 285 secured to the adjacent end of the platen, as represented in Figures .1 and 13. 286 represents an intermediate actuating lever which is pivoted on the lower part of the front carriage-arm 261 which is adjacent to the ratchet wheel 285. The ratchet lever is connectedv with the intermediate lever by means of a link 287 which is pivoted at is upper end to the rear arm of the ratchet lever and is provided at its lower end with a loop 288 which receives the rear arm of the intermediate lever. 289 represents a spring which connects the front arms of the ratchet lever and intermediate lever. The upper end of this spring is connected with the front arm of the ratchet lever a greater distance from the pivot of the latter than the distance between the connection of this spring with'the intermediate lever and the pivot of the latter. By this connection of the spring 289, the leverage of the ratchet lever is greater than that of the intermediate lever, which causes this spring, when both of these levers are free, to turn these ing mechanism'andprovided at opposite ends raising their rear arms, thereby moving the ratchet pawl upwardly or backwardly for taking up a new tooth on the ratchet wheel.

The ratchet pawl is yieldingly held in engagement with the ratchet teeth by means of a spring 290. The movement of the intermediate lever in the direction for raising its rear arm and moving the ratchet pawl backwardly is limited by means of a nose 291 formed on this lever and engaging with a stop on the adjacent arm of the carriage, as represented in Figure 13.

The rocking. motion of the intermediate lever is always the same, and in order to enable the same to turn the platen different distances, the rear arm of the intermediate lever is provided on its under side with a number of notches 292 which are arranged different distances from its fulcrum, and one or another of which is engaged by the lower end of theloop 288 on the connecting link 287.

Upon engaging this loop with the notch of the intermediate lever nearest its axis, the ratchet pawl is shifted so that the platen is turned one line-space at a time; while upon shifting this loop into engagement with one of the outer notches of the intermediate lever, the platen will be turned forward by its ratchet mechanism a corresponc'iingly greater distance by the operation of the machine.

The intermediate lever is turned in the direction for shifting the platen by a transverse bar 293 arranged below the front arm thereof, as represented in Figures 1, 2, 7, 13,

and 18. This bar is supported upon the upper ends of two rock arms 294 which are mounted loosely with their lower ends on the cross bar 167. 295 (Figs. 13 and 18) represents a depending arm which is preferably formed in one piece with that one of the arms 294 arranged on the left-hand side of the machine. This depending arm is provided with a nose which is arranged in rear of and in the path of the rocking frame 29.

During the last portion of the rearward movement of this rocking frame, it engages with the nose of the depending arm 295 and moves the same rearwardly, and the upper arms 294 connected therewith are moved forwardly, thereby causing the cross bar 293 to be carried upwardly and turn the intermediate lever in the direction for feeding the platen and paper forwardly. During the forward movement of the rocking frame 29, the rock arms 294 are turned backwardly together with the intermediate lever and connecting parts by the spring 289 preparatory I to feeding the platen forward the next space.

As the line-spacing 'of the record sheet by printe and in the same operation in which said item is printed, the printed record is' feedin the platen occurs after each item isand the mechanism shown for this hand when it is desired to adjust the paper, this being affected by releasing the pawl 284 from the ratchet wheel and then turning the platen by means of a button 296 secured to one end of the shaft, as shown in Figures 1, 16, and 18. The cross bar 293 extends a sufficient distance transversely of the machine so as to engage with the front arm of the intermediate rock lever 286 in all the positions to which the paper carriage can be shifted transversely in the machine.

Horizontally movable carriage The paper carriage is capable of sliding lengthwise on the rods 263 and 265 fofpresenting different parts of the paper to any series, as shown in Figure 17. The catch 302 is pivoted on the rod 167 and is yieldingly held 1n engagement withany one of the notches in the adjusting sleeve 3011 by a spring 305. When it is desired to shift the carriage intermittently short distances lengthwise of the platen for writing narrow columns, the adjusting sleeve is turned so as to present its closely spaced notches to the catch, and the latter is shifted from one of these notches to another as the writing progresses. When wider-columns are to be written the adjusting sleeve is turned so as to present correspondingly wider spaced notches to the catch. As shown in the drawings,

only two series of adjusting notches are provided on the adjusting sleeve, but more series of notches may be rovided if necessary.
